For several years, graham has gathered data on students who own a computer and on their performance on a typing-speed test. he creates the linear model  y  =  3.8x  +  17.4 where  y  represents the typing speed, in words per minute, of a student and  x represents the number of years the student has owned a computer. according to graham’s model, what is the approximate speed of a student who has owned a computer for three years?

B) 29 words/min

Step-by-step explanation:

Equation : y = 3.8 (x) + 17.4

The 'X' value equals the three years (3 years)

New Equation: y = 3.8 (3) + 17.4

Step 1: 3.8 (3) = 11.4

Step 2: 11.4 + 17.4 = 28.8

Step 3: ROUND YOUR ANSWER TO THE NEAREST TEN So, 28.8 then becomes 29.

Step 4: Therefore, your answer is B) 29 words/min

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
